Imasara desu ga, Osananajimi wo Suki ni Natteshimaimashita

I've known Ta-kun ever since we were 10 years old. Even though we are now in high school, we still spend our days in his room, talking about nothing in particular. We are close, but our relationship is not quite as sweet as lovers… Why won't you notice me? I'm trying so hard to get closer to you! I am Hikari Shirasaka, 16 years old… It might be a little late for me to tell you this, but I think I've fallen in love with you, my childhood friend.
